Definitions

  • the present invention relates to cold-set adhesives for a cold corrugation system.
  • starch adhesives comprising corn starch prepared by a Stein-Hall process are conventionally used.
  • a liquid mixture composed of a carrier solution and a main slurry is used as the liquid adhesive, but preparation of the liquid mixture is complicated.
  • the liquid adhesive is applied to flute tips of the corrugating medium and then liners are adhered to the corrugating medium.
  • solidification of the liquid adhesive is carried out by the so-called hot-corrugation system, which comprises compulsorily heating, by means of hot plates heated to from about 150° C. to 160° C.
  • U.S. Pat. No. 4,094,718 has disclosed an adhesive comprising a powdered polyvinyl alcohol together with starch.
  • This adhesive is prepared by dispersing a finely divided powder of polyvinyl alcohol in an aqueous solution of starch, which essentially is an improved variation of the Stein-Hall process. In this case, it is also necessary for solidification of the adhesive to compulsorily heat by means of hot plates. As described above, since much heat energy is consumed in Stein-Hall process today, economical problem is caused by energy consumption.
  • the gelatinized adhesive is the so-called irreversible gel that the adhesive does not become liquid even if heated again to 90° C. or more, when it is once gelatinized.
  • a cold-corrugation system using the abovedescribed cold-set starch adhesive for corrugated board has been reported by Clude H. Sprague in Tappi, Vol. 62, No. 6, pp. 45-48 (1979). However, it has not been put to practical use up to the present time. There are problems with such a system, viz., that the initial adhesive property during the period from adhesion of the corrugating medium to liners to the process by a slitter is poor, and the liquid adhesive does not sufficiently premeate into the paper.
  • An object of the present invention is to provide adhesives for paper which have a cold-setting property.
  • the present invention relates to cold-set adhesives for paper consisting essentially of polyvinyl alcohol (hereinafter referred to as PVA), a filler, a water-soluble boron compound, and water.
  • PVA polyvinyl alcohol
  • a filler a filler
  • a water-soluble boron compound a water-soluble boron compound
  • adhesives have properties such that they are liquids having fluidity capable of application to paper by means of roll coater at 60° C. or more but lose their fluidity by cooling to a room temperature to gelatinize.
  • starch adhesives when the adhesives are once gelatinized, they do not become a solution again even if the temperature is elevated by reheating.
  • the adhesives of the present invention have the characteristic that they show the so-called thermally reversible gel-sol behavior (viz., that the gelatinized adhesives become a solution having nearly the same viscosity as that of the original state when the temperature is re-elevated to 60° C. or more). Accordingly, cleaning of conduits is easily carried out, because the adhesives become a solution again by heating even if they gelatinize in the conduits.
  • the adhesives of the present invention have an excellent film forming property and high film strength as compared with starch adhesives, and as a result, the adhesive strength thereof is high. Further, their water resistance is superior to that of starch adhesives. However, even though the water resistance of the adhesives of the present invention is excellent, recovery of waste paper is not difficult, because the adhesives are soluble in water, which distinguishes them from the prior adhesives comprising cross-linking type water-soluble resins or hot melt adhesives.
  • the adhesives of the present invention are more economical than synthetic resin emulsion adhesives or hot-melt adhesives, and they can compete economically the starch adhesives.
  • the adhesives of the present invention When the adhesives of the present invention are applied in a liquid state to paper at a high temperature and adhesion is carried out just after application, they are solidified within a short period of time of less than about 30 seconds, and complete adhesion, which is determined by the tearing of paper by the adhesion test described below, can be easily obtained. Accordingly, it becomes possible to carry out high-speed adhesion at a rate of 150 m/min or more.
  • the use of hot plates as required in the case of producing the prior art production of corrugated board is not necessary, because heating is not necessary for solidification of the adhesives, and, consequently, economy of heat energy can be practiced. Further, they are desirable adhesives from the viewpoint of improvement of quality and improvement of processing properties, because they do not cause nonuniform distribution of water in the papers or warping of corrugated board due to heating.
  • FIG. 1 is a graph which shows the temperature dependence of viscosity in an example of adhesives of the present invention together with comparative examples.
  • FIG. 2 is a graph which shows, for various adhesives, the relation between viscosity at 60° C. of the adhesive and the time required for complete adhesion.
  • the adhesives of the present invention consist essentially of PVA, a filler, a water-soluble boron compound, and water. It is necessary to consider the following matters with respect to the initial adhesive property, adhesive strength and viscosity of liquid adhesive.
  • PVA used in the present invention those having an average degree of polymerization of from about 500 to 3,000, and a degree of hydrolysis of about 80 mol% or more are preferred. Particularly, PVA having a saponification value of about 97 mol% or more is preferred because of its water resistance. PVA having about 1,000 to about 2,000 of the average degree of polymerization is preferred in respect of adhesive strength and processing property. The average degree of polymerization and the degree of hydrolysis of PVA are measured by the following tests.
  • filler used in the present invention there are, for example, clays such as kaolinite, sericite, pyrophyllite, montmorillonite or talc, etc., and inorganic fillers such as calcium carbonate, satin white, titanium dioxide, aluminium hydroxide, barium sulfate, calcium sulfate, magnesium oxide or magnesium hydroxide, etc. Among them, those which show alkalinity in an aqueous dispersion are preferred, and, particularly, calcium carbonate is the most suitable filler.
  • clays such as kaolinite, sericite, pyrophyllite, montmorillonite or talc, etc.
  • inorganic fillers such as calcium carbonate, satin white, titanium dioxide, aluminium hydroxide, barium sulfate, calcium sulfate, magnesium oxide or magnesium hydroxide, etc.
  • inorganic fillers such as calcium carbonate, satin white, titanium dioxide, aluminium hydroxide, barium sulfate, calcium sulf
  • water-soluble boron compound used in the present invention there are, for example, boric acid, borates such as borax, etc., and boric acid esters of polyhydric alcohols such as glycerine or ethylene glycol, etc.
  • boric acid is preferred.
  • combinations of boric acid and basic fillers such as calcium carbonate, etc. are the most preferred for the purpose of the present invention from the viewpoint of cold-setting properties, adhesive strength, and costs.
  • the adhesives of the present invention it is possible to add other additives within ranges which do not damage the basic properties of the adhesives, for example, defoaming agents such as polyoxyalkylene glycol derivatives, alkyleneglycol aliphatic acid esters or polyethylene oxide-polypropylene oxide copolymers, etc., paper permeating agents such as anionic surface active agents, etc., antifungal agents composed of organic nitrogen and sulfur containing substances, and plasticizers such as polyhydric alcohols such as glycerine and esters thereof, etc.
  • defoaming agents such as polyoxyalkylene glycol derivatives, alkyleneglycol aliphatic acid esters or polyethylene oxide-polypropylene oxide copolymers, etc.
  • paper permeating agents such as anionic surface active agents, etc.
  • antifungal agents composed of organic nitrogen and sulfur containing substances etc.
  • plasticizers such as polyhydric alcohols such as glycerine and esters thereof, etc.
  • adhesive components it is possible to add cellulose compounds such as starch, etc., and chemically modified products thereof, water-soluble resin such as polyacrylic acid or polyacrylamide, etc., and inorganic compounds such as water glass, etc., within the range of not damaging the cold-setting property.
  • the adhesives of the present invention are liquid at a high temperature, but the viscosity thereof rapidly increases as the temperature decreases, and the adhesives gelatinize as the temperature falls to room temperature (20° C.).
  • the resulting gelatinized products are thermoplastic which can be converted to the liquid state again by raising of the temperature.
  • those having a viscosity of from about 100 to 2,000 centipoises, particularly, 100 to 1,000 centipoises, measured at 60° C. by a Brookfield revolving viscosimeter are preferred. If the viscosity at 60° C. is less than 100 centipoises, permeation of the solution into the paper layer becomes too large, causing poor adhesion, because the adhesive layer on the paper surface is thin.
  • the adhesives gelatinize before cooling to 20° C. If additives which do not gelatinize at 20° C. are used, 1 minute or more of the setting time is required for adhesion. For example, in the case of utilizing them in a process for producing corrugated board, a shear of adhesion parts may be easily caused during transfer to the next process, if the production rate of the corrugated board is not reduced.
  • the mixing ratio of PVA to the filler is in the range of from about 20/80 to about 70/30 (parts by weight). If PVA is less than about 20 parts by weight, adhesive strength tends to be reduced. On the other hand, if it exceeds about 70 parts by weight, the temperature dependence of viscosity becomes small, and the adhesives are economically disadvantageous.
  • the amount of the water-soluble boron compound is in the range of from about 0.2 to 4 parts by weight, and preferably from 0.3 to 2 parts by weight, per 100 parts by weight of PVA and filler (that is, the total weight of PVA and filler).
  • the amount of the water-soluble boron compound is less than 0.3 part by weight, temperature dependence of viscosity of the aqueous solution tends to be reduced. On the other hand, if it exceeds 2 parts by weight, permeation of the solution into the paper layer tends to deteriorate because of increasing the viscosity of the solution, by which inferior adhesion is easily caused.
  • the adhesives of the present invention can be prepared, for example, as follows. To a blender equipped with a stirrer, PVA, a filler, and a water-soluble boron compound are charged, preferably in the order listed. After mixing homogeneously, water is added to the resulting mixture, and the mixture is dissolved by heating to 90° C. or more. In this case, viscosity of the resulted solution is measured by means of, for example, a Brookfield revolving viscosimeter while varying the temperature, by which, for example, composition of the mixture or solid content in the aqueous solution is suitably controlled so that the solution shows a cold-setting property and, preferably, the viscosity at 60° C. is from 100 to 2,000 centipoises and the solution gelatinizes before cooling to 20° C.
  • the adhesives of the present invention are in a gelatinized state at a room temperature, which have neither fluidity nor adhesive property. However, when they are heated, they become a fluid as the temperature increases, to form a solution having the viscosity (100 to 2,000 centipoises) rendering them capable of application to paper at 60° C. Accordingly, in the case of practically utilizing them for adhesion of paper, for example, a solution heated to 90° C. or more is applied to paper at from about 60° C. to 80° C., and is gelatinized to complete the adhesion. If the solution is gelatinized by cooling, it can be applied to paper by reheated to 60° C. or more.
  • Permeability of the liquid adhesive into paper to be applied depends on the degree of sizing, bulk density, presence or absence of a surface coat, and basis weight. Therefore, in the case of requiring an improvement of permeation, the liquid adhesive is heated to about 80° C. and applied to the paper, which is also preheated.
  • the adhesives of the present invention it is preferred to increase the solid content of the liquid adhesives to reduce the amount of water to be introduced into the paper, by which warps of the produced corrugated board sheets can be diminished.
  • the adhesives of the present invention are preferred to have about 20% or more by weight of the solid content. In this case, it is of course preferred that the viscosity of the liquid adhesives at 60° C. is in the range of from about 100 to 2,000 centipoises.
  • FIG. 1 the temperature dependence of the viscosity in the adhesives of the present invention is shown together with that of comparative examples.
  • the compositions of the adhesives in this case are shown in Table 1.
  • FIG. 2 the relationship of the viscosity at 60° C. of the adhesives and time necessary to carry out complete adhesion in the case of allowing to adherence to liners (basis weight: 360 g/m 2 ) is shown mutually.
  • the compositions of the adhesives in this case are shown in Table 2.
  • the production rate of corrugated board is generally from 60 to 200 m/minute, adhesion of flute tips of the corrugating medium to the liner sheets causes stripping or shear in the next process (slitter or cutter), if complete adhesion does not conclude within less than a minute (preferably less than 40 seconds) after being brought into contact.
  • the amount of boric acid is particularly preferred to be in the range of from about 0.3 to 2.0 parts by weight.
  • the viscosity at 60° C. of the adhesive is important to be in the range of from about 100 to 2,000 centipoises, and preferably from 100 to 1,000 centipoises.
  • a solution of the adhesive for example, is applied by means of a roller coater (Plane roller or Anilox roller) so as to be, preferably, 5 g/m 2 or more of the solid content, and the papers are brought into contact at once. After brought into close contact, cold-setting adhesion is carried out by cooling to room temperature.
  • the paper applied may be at room temperature or may be heated to more than room temperature.
  • the adhesives of the present invention are used for papers, and can be utilized for adhesion of various kinds of papers.
  • they can be suitably used for production of corrugated boards, laminating boards, cartons, cases and paper tubes, etc.
  • corrugated boards are very useful for saving energy cost and improving quality of the corrugated boards.
  • they can be used, of course, for adhesion of paper to other materials, such as paper to leather, paper to wood or paper to metal, etc.
  • this aqueous solution was heated to 70° C., it was applied to a surface of a liner having 360 g/m 2 of the basis weight so as to be about 50 g/m 2 of the coating amount. Then, the surface to which the aqueous solution was applied was immediately brought into contact with another liner of the same quality, and they were allowed to leave under 250 g/cm 2 of load at room temperature, by which complete adhesion such that paper layers were torn under peeling test was obtained after 20 seconds.

  • Adhesion of liners was carried out using this solution by the same manner as described above, but complete adhesion could not be attained after 60 seconds.
  • 35 parts by weight of PVA having an average degree of polymerization of 630 and a degree of hydrolysis of 98.5 mol%, 64 parts by weight of a finely-divided powder of calcium carbonate, and 1.0 part by weight of boric acid were uniformly mixed using a blender.

  • the same aqueous solution as the above-described adhesive was prepared, except that the concentration was 22.5% by weight.
  • This aqueous solution had a viscosity of 40 CPS at 60° C. and did not gelatinize at a room temperature.
  • Adhesion of liners was carried out using this solution in the same manner as described above, but complete adhesion could not be obtained after 2 minutes. The reason is believed to be that the adhesive excessively permeates into the paper layer at application, because the viscosity of the adhesive is too low, and consequently the adhesive layer left on the paper surface becomes very thin.
  • 35 parts by weight of PVA having an average degree of polymerization of 630 and a degree of hydrolysis of 98.0 mol%, 63 parts by weight of a finely-divided powder of calcium carbonate, and 2 parts by weight of boric acid were uniformly mixed with using a blender.
